NHS is essential for organization of the circumferential actin ring. (A) Knockdown of NHS in Caco-2 cells resulted in larger cells, loss of a cuboidal cell shape and a diffuse localization of α-catenin (green) at the cell periphery. Scale bar 10 µm. Nuclei stained with DAPI (blue). (B) NHS siRNA treatment resulted in a 2.5-fold increase in cell area. For each condition, 100 cells from two independent experiments were measured. Error bars are ±standard deviation. (C) The thick circumferential ring of actin bundles (counterstained for F-actin, green) aligned with the cell borders was disrupted in NHS-depleted cells. Nuclei stained with DAPI (blue). Scale bar 10 µm.
